T all whom it may concern:

- Be'it known that I, Fnrrz C. Lucnr. bAir,

of New York city, in the county and State of New York, haveinventedeertain new .and useful Improvements in Line-Casting Machines,of which the following is n specificat-ion. i I

These improvements in line casting ma: chines have to do with the moldin which the slug or'line is case-said mold being a travelinginold,which moves from casting to ejecting position and return, as usual inmachines orihis class; and they relate more particularly to a travelingmold ofv this character which is varis'bleas to the length and width ofits mold space and is combined with suitable means for automaticallyclosing the mold to one 'len th and width or another as required, and aso with means for automatically opening themold in both directionsduring its travel. A mold of this general character is not here broadlyclaimed, inasmuch as I have made it the subject of my patent forimprovements in line casting machines, No. 944,981 of December 28, 1909.In the mold of my said patent the closin of the mold to predeterminedlengthand width, takes place through the agency of spring actuated meanswhich automatically o crate as soon as the mold, on its return movementfrom ejecting to casting position, quitsthe devices by which it isopened in both directions. In my present application, in lieu of saidspring actuatedv means, I employ stops which operate not onlyautomatically but positively to close the urold to. redetermined lengthand widththis action taking place near" the close of the returnmovement'of the mold from ejecting to casting position; and these stopsI unite with independent ad usting means whereby the sto 5 may be set toclose the mold antomatical y and positively to varying lengths andwidths as required. 'In this way the action of-the parts of the mold isrendered more certain and accurate, and I am cnabifed to dispenseentirely with spring actuated .mold closing devicesn point of somepractical importance, inasmuch as the heat due to the casting operationis apt to have an injurious influence on the springs used for thispurpose.

In the drewings'G is the carrier frame.

F is the slide mounted in the carrier frame and adapted to slide'thercinfor the zurpose of convcyingzrhe mold from. cast- .llfi to ejectingposition and return. r I ihe mold consists of the cotton and top jaws l,2, mounted in the slide, and the 7 sprin -impelled spring yielding sidepieces 3 an ,5 housed in and interposed between the jaws. These pieces.which form. the, eside walls of the mold, sre housed, the one, I 3, 1nthe lower aw, and the other, 5, n the upper jaw. They are spring pressedby springs 4 and 6. each to ard lhe'fucc of the. opposite jaw, andthey-form tight filing side wallswhich are self sting to verity tions inriLiiniir-t; l'etween he top and botion: jaws.

The slide l is held and guided in its movetudinul rib 30 on its'top,which enters u corresponding grlimve in the carrier frame; and, by a.rib 22 on itsbottczn, which enters .1 corresponding 3, grt' ove in thebottom to the carrier frame. ll-ih is formed as a rack to engage apinion 21 mounted in by which the slide may be moved at proper intervalsfrom custingto ejecting position and return.

The parts thus far described are the some my aforesaid Patent No.944,981.

In order to open and close the mold, I provide the wedge 15, with anupwardly 23, 23 againstwhich alternately the linger between castingsndejecting position. V The linger 15 corresponds to the like designatedpart in my aforesaid Patent No. 9-l .95l. It extends up from the Wedgethrough a slot in the slide F and projects into 3. longitudinal channelformed in the top of the rib 30.

The stop 23, corresnoncls in purposeand function to the. like designatedpart in my suidPatent No. 99 931. As the moldmoves to the right from theposition shownin Fig. l to ejecting position, the stop 23 meets thefinger 15', and thus arrests the wedge 15, slightly before the moldreaches eg'eciing. osition, in this way relieving'the upper In order toagain close the mold the stop 23' is so located t-lirit' on the returnof the. mold from ejecting to rusting position itmeets the finger 15-and thus arrest-s the wedge 15 slightly before the mold reaches castingposition; andus the wedge isthus held stationarywhile the mold stillcontinues wedge positively forces down and closes the pressed isdetermined by the position of the stopv 23' relzitivel to the finger.15", and therefore by making this stop 23'- adjustable so that it willmeet the finger 15" sooner or later during the return movement of the asdesired. Obviously such edjustment can be provided for in many Ways. Iprefer for this purpose toforin both sto s 23, 23 on, or firthem to, abar a, at a from each other slightly less than the length of traverse ofthe slide, the her being adjustistance apart ably secured to the top ofthe carrier frame G by thiunb screw or bolt 3' which passes into thetopof the frame through longitudimi slot 3 in the bar. The stops projectdown through slots in the carrier frame into the path'of moieuient ofthe finger 15". By aefiusting the our lengthwise of the-frame Gr theposition of the closing stop 23 can be varied at will to determine thewidth of the mold. space. At the same'tinie, inasmuch as the distancebetween the two stops 23, 23 is invariable, it follows that no matterwhat may be the width o1 the slot, the 0 ening movement of the mold willalways e the some.

To open and close the mold lengthwise, and to vary the length of theslot, I use a similar system of stops in connection with the lower jaw,with the difference, however, that in this case the two stops are notconnectcd so as to be adjustable together, but

the closing stop is adjustable-dude endently ofthe opening stop, \vlnch:ndee' may he,

' and preferably is, a fixed stationary stop, by .the'acnon or which themold space is opened always to its maximum length, whatever may be theposition of the closing stop. Munifestly the structural details ofdevices for this purpose inoywvidel vary Under the arrangement shown int. e drawing, the stationary opening stop is formed by the vertical our6 which is seen ed to the top and bottom rails of the carrier frame Gand extends in front, and crosswise The closing stop consists of ahorizontal rod t, parallel with the face of the mold and mounted in :1vertical bar f which, like the vertical bar t, is secured to the top andbottom rails of the carrier frame G. The end of o f the mold.

closing stop rod 25, and the verticul opening I bar t, are in the pathof movement of :1 finger'or other projection 'r on the lower aw 1.

In order to adjust the sto') bar 15 so that it shall meet. the finger asooner or" later during thercturn movement of theimold from ejecting tocasting position, the stop her fits in a horizontal undercut guidegroove on the innot face of the arm t wherein it can move lengthwise;and it is held in adjusted position by a set or clamp screw 15, as shownmore clearly in Fig. 7. Thus by varying the position of 'ie closing stot-', the length of the mold slot or space can e varied at pleasure. Butwhatever the length of, the mold slot when closed, itwill always beopened by the stationary stop 6 to the same extent-tlmt is, to themaximum length.

i may connect the two stops t, t for the lengthwise opening and closinjust as the two stops-23, So, For the widthwise opening and closing areconnected; or I may make the two stops :23, 23 separate, and withseparate provisions-tor adjustment. 4 i

It is not important that the widthwise opening stop 23 be adjustable,any more than in tht case of the lengthwise opening stop t. But it isessential. that the closing stop 23' should be both longitudinallyadjustable and combined with means for hold ing it rigidly-andunyieldingly in its adjusted position. The capacity for lengthwiseadjustmentis essential because thereby the width of the slot isdetermined; and. the stop in whatever position it may be set must berigid and unyielding, because it cannot otl erwisefinsin'e the accuracyof closing which is indispensable to good work. The

arrangement, however, which on the whole- I prefer isillustrated in thedrawing. Ob-

viously these and other structural details of the mold can be. widelyvaried by the skilled mechanic without departure from the spirit ofmyinventiom' I therefore do not'limit myself to the particular detailsof construction herein shown and described in illustration of myinventionz'But What I claim and desire toseeure by Letters Patent is asfollows: a

1. A linotype mold mounted to recipro cate bodily and comprising, incombination,

ing the upper jaw, stops 23 23' for automatically and positively movinghe. wed 'e in relation to the other parts as the mo d moves to and fro,and means for adjusting said stops.

3. The reciprocating linotypemold ineluding the wedge to vary the widthof the mold space in combination with a front stop to move the wedge ina direction to ermit the mold to open, a rear stop longitut inallyadjustableto move the wedge in a direction and to an extent to close themold to any predetermined widthaand means for holding the rear stoprigidlyv in adjusted position.

.4. A longitudinally reciprocating linotype mold having one membermovable longitudinally in relation to the others for the purpose ofchanging the length of the mold space in combination withstops forautomatically and positively opening and closmg the mold to one lengthor another durin its movement to and fro.

5. A longitudinally reciprocatin linotype f mold having one membermovable longitudinally in relation to the others for the pur pose ofchanging the length of the mold space, in com ination' with a fixed,stop for automatically opening the mold to maximum length, and anadjustable stop for automatically closin the mold to one length oranother as desire 6. Ina line casting machine, a traveling mold variableas to the length and width of the mold space in combination with adjustable means for automatically and positively closing the mold to onelength and width or another as required, and means for automaticallyopening the mold in both direc-' tions during its travel. 7
